Use full path
It's very wierd.
Can you try
echo 00000 | /usr/bin/egrep ....
just to avoid path suspisions?

measurefs.reiser4
measurefs.reiser4(8) reiser4progs manual measurefs.reiser4(8) NAME
measurefs.reiser4 - the program for measuring reiser4 filesystem parameters (fragmentation, node packing, etc.). SYNOPSIS
measurefs.reiser4 [ options ] FILE DESCRIPTION
measurefs.reiser4 is reiser4 filesystem measure program. You can estimate reiser4 filesystem fragmentation, packingm etc. structures by using it. COMMON OPTIONS
-V, --version prints program version. -?, -h, --help prints program help. -y, --yes assumes an answer 'yes' to all questions. -f, --force forces measurefs to use whole disk, not block device or mounted partition. -c, --cache N sets tree cache node number to passed value. This affects very much behavior of libreiser4. It affects speed, tree allocation, etc. MEASUREMENT OPTIONS
-S, --tree-stat shows different tree statistics (node packing, internal nodes, leaves, etc) -T, --tree-frag measures total tree fragmentation. The result is fragmentation factor - value from 0.00000 (minimal fragmentation) to 1.00000 (maxi- mal one). Most probably, this factor may affect sequential read performance. -D, --data-frag measures average files fragmentation. This means, that fragmentation of each file in filesystem will be measured separately and results will be averaged. The result is fragmentation factor - value from 0.00000 (minimal fragmentation) to 1.00000 (maximal one). Note, that for the fresh filesystem (created not very long time ago) and even fully filled by data, this value will be pretty small. -F, --file-frag FILE measures fragmentation of the specified file. The result is fragmentation factor - value from 0.00000 (minimal fragmentation) to 1.00000 (maximal one). Note, that fragmentation of a small file (depends of used tail policy), which consists of tail items, is not very reliable value. That is because, they is always afoot due to balancing. Examples: measurefs.reiser4 -F /usr/bin /dev/hda2 measurefs.reiser4 -F /bin/bash /dev/hda2 -E, --show-file show file fragmentation for each file if --data-frag is specified. PLUGIN OPTIONS
-p, --print-profile prints the plugin profile. This is the set of default plugins used for all parts of a filesystem -- format, nodes, files, directo- ries, hashes, etc. If --override is specified, then prints modified plugins. -l, --print-plugins prints all plugins libreiser4 know about. -o, --override TYPE=PLUGIN, ... overrides the default plugin of the type "TYPE" by the plugin "PLUGIN" in the plugin profile. Examples: measurefs.reiser4 -o nodeptr=nodeptr41,hash=rupasov_hash /dev/hda2 REPORTING BUGS
